Markdown (marked.js) +

M↓
<!----------------- your text.md here -------------------> Usage: Open (above) text box, edit it, run markdown **`[M↓]`**, and export HTML. Some tests for `marked` and `mathjax` ---- Help in short: * <https://marked.js.org> * <https://github.github.com/gfm/> (MD + tables, task list items `[x]`, strikethrough `~~`, autolinks `<...>`) * <https://commonmark.org/help/> ### How it works? text → [**Markdown**](https://marked.js.org) (with code [highlighting](https://highlightjs.org/)) → [x] [**MathJax**](https://www.mathjax.org/) → preview (+ HTML export) Uses async. working MathJax (see also <https://github.com/kerzol/markdown-mathjax>). ### Math Inline <https://docs.mathjax.org/> * AsciiMath2jax (`''`) - see <http://www.wjagray.co.uk/maths/SymbolList.html> and use double "`''`" = `MathJax.Hub.Config({ asciimath2jax: {delimiters:...`: '' sum_(k=1)^n k = 1+2+ cdots +n=(n(n+1))/2 '' _ _ _ '' int_0^oo (x^3) / (e^x-1)\ dx = (pi^4)/(15) '' _ _ _ ''f'(x) = dy/dx'' '' ( a bc\ d ) \ \ [[a,b],[c,d]] '' ''((n),(r))''; _ _ _ ''A_(m,n) = ((a_(11), cdots , a_(1n)),(vdots, ddots, vdots),(a_(m1), cdots , a_(mn)))'' * TeX2jax (`$`, `$$`): ... $\(ax^2 + bx + c = 0\)$ ... **in**line ... $\left(\begin{array}{c} n \newline r \end{array}\right)$ = ... $$ \begin{equation} \int_0^\infty \frac{x^3}{e^x-1} dx = \frac{\pi^4}{15} \label{eq:sample} \end{equation} $$ <div>$$ A_{m,n} = \begin{pmatrix} a_{1,1} & a_{1,2} & \cdots & a_{1,n} \\ a_{2,1} & a_{2,2} & \cdots & a_{2,n} \\ \vdots & \vdots & \ddots & \vdots \\ a_{m,1} & a_{m,2} & \cdots & a_{m,n} \end{pmatrix} $$</div> Problems 1. "`\`" before any ASCII punctuation character is [backslash escape](https://github.github.com/gfm/#example-301), so "`\\`" (or "`\,`") should be written as "`\\\\`" (or "`\\,`") or block can be placed inside `<div>` tag. You can temporary switch off MathJax to see text after Markdown conversion. 2. MathJax without `["resetEquationNumbers",MathJax.InputJax.TeX]` (in `MathJax.Hub.Queue()`) - TeX math block `$$` is broken on second MathJax conversion. <!-- --> ### Extensions ~~strike through~~ (`~~`) <http://xy.z> <abc@xy.z> #### tasklist - [x] foo - [ ] bar - [x] baz - [ ] bim ### Code ```markdown #### tasklist - [x] foo - [ ] bar - [x] baz - [ ] bim ``` ````python if i > 0: print(f''' i = {i} 2i = {2*i}''') ```` text `and code ` . . . - - - - - #### Local images (relative path)  ``  ``  `` (it works in some clouds) <img src="./MarkdownIcon.png" alt="MarkdownIcon" width="30" onload="alert('DOMPurify.sanitize() ERROR!');"/> `<img src="./MarkdownIcon.png" width="30"`... <img src="./MarkdownIcon.png?raw=1" alt="MarkdownIcon" width="30"> `<img src="./MarkdownIcon.png?raw=1 width="30""`... #### HTTP image  - - - - - #### Tabels header | _Pipe_ | table -------|-------:|:-----: 0 | 1 | 2 3 | 4 | 5
